OEM & custom glass
Custom borosilicate glass, from the material up
We melt and draw our own H‑32 borosilicate tubing, then form it. That means a custom part is not assembled from someone else’s material — composition, dimensional consistency and continuity of supply stay under one roof for the life of the program.
Capability
What we can make
Most inquiries fall into one of three shapes. If yours does not, describe the function rather than the part — we will tell you honestly whether glass is the right answer.
01 / FORMING
Formed vessels
Blowing, drawing and shaping from our own tubing — vessels, funnels, tubes and containers to your drawing or to a functional brief.
02 / JOINING
Tube joining & sealing
Joining tubes of differing diameter, adding necks, joints and threads, and sealing. This is the step that turns a standard form into a part specific to your process.
03 / MATERIAL
Tubing & blanks
If you do your own forming, we can supply H‑32 tubing and semi-finished blanks by the length or by the piece. See blanks →
Process
How an inquiry becomes a supply program
Tell us the requirement
A drawing is ideal, but a sketch, a photograph of an existing part, or a description of what it has to do is enough to start.
Feasibility & indicative cost
We come back on whether the geometry is achievable in borosilicate glass, at what tolerance, and what the volume economics look like. If it is not feasible, we say so at this stage.
Prototype
A sample piece for you to evaluate in the real application, with dimensions confirmed against the drawing.
Production & scheduled supply
Repeat production against a schedule, with inspection certificates and English shipping documentation as required.
Track record
Three kinds of problem we have solved
Detailed case studies are published on our Japanese site. In outline:
CASE 01
A filtration funnel for a laboratory equipment maker
An existing form re-engineered so it could be produced reliably at the volume the customer needed.
CASE 02
A beaker used as retail packaging
Laboratory glassware adopted as the container for a food product — a case where the look of the labware was the point.
CASE 03
A joined-tube vessel for a distiller
Tubes of different diameters joined to produce a vessel that could not be formed in one piece.
Send us the part you cannot get made
Drawing, sketch or description — whichever you have. We will come back with a feasibility answer, not a brochure.
